I am not a coffee lover, I am more of a tea person however, a taste of the world's most expensive coffee changed that. What type of coffee that possesses the power to alter my taste buds? It is none other than the world-renowned 'kopi luwak' a.k.a civet coffee. Kopi luwak is produced mainly on the islands of Sumatra, Java, Bali and Sulawesi in the Indonesian Archipelago. Bali has a few of these coffee farms scattered all over the island, especially in Ubud.
